' 3 Claims.

The present invention relates to multiple spools and to thread packages formed thereon.

An object of the invention is to provide a multiple spool which is inexpensive to manufacture, easy to wind and can be readily shipped.

Another object of the invention is to provide a spool and thread package of the type described in which the spool and thread thereon may be readily severed into individual spools for use as desired.

Another object of the invention is to provide a Ispool having flat sides which may be readily mounted in a winding machine to permit multiple thread packages to be formed thereon at high speed.

A still further object of the invention is to provide a spool having a construction wherein a spreader may be inserted longitudinally of the spool to bow the flat sides of the spool intermediate the edges thereof to provide a spindle-receiving bore therein whereby the spool may be readily mounted on a sewing machine or the like.

Other features and advantages of the invention will be apparent from the specification and claims when considered in connection with the drawings in which:

Figure l shows a plan view of the multiple spool with the longitudinally spaced windings thereon.

Fig. 2 shows an end view of the spool with the winding in place.

Fig. 3 shows one of the spools severed from the multiple spool with a spreader inserted therein to form the spindle-receiving portion.

Fig4 shows an end view of Fig. 3 with the spreader in position.

As shown in the drawings the multiple spool of the present invention comprises flat surface members I and II spaced apart in parallel planes by means of a filler I2. While the filler may take many forms, it is at present preferred to form it as a corrugated member arranged between and secured to the surface members IIJ and II so that the corrugations extend longitudinally of the spool.

In the preferred form of the invention the members I0, II and I2 are formed of paper. By the use of the term paper herein it is intended to cover various types of fibrous sheeting, paper cardboard, chip board and other similar material.

As shown in Fig. 1 the side edges of the spool are provided with opposed notches I3, each pair of opposed notches forming a threadreceiving portion I4 with the portions I5 of the 2 spool adjacent the notch, forming, in ee'ct, flanges extending between the winding portions.

With the spool of the present invention being formed by parallel flat surface members spaced by a ller having a longitudinally extending passage therethrough as formed by the corrugations, it can be easily vand readily mounted on a winding mandrel and chucked on a winding machine to permit simultaneous winding of a thread package I6 on each of the threadreceiving portions I4. After the packages are completed, the ends I'I of the thread are brought together and fastened in a slit I8 formed in one of the flange portions.

It will be seen that such a multiple spool is substantially flat and will occupy a minimum of space in shipping. Furthermore, with the corrugations extending longitudinally throughout the spool, it is reinforced against bending transversely of the longitudinal extent of the spool during shipping and handling so that the spool will maintain its flat relationship.

When it is desired to use one of the spools, it is merely severed along the line extending through the flange portion and the corresponding end I1 so as to produce an individual spool such as shown in Fig. 3. This spool may be used in this condition where it is merely required as a thread storage device. However, it may be arranged so as to be mounted on a sewing machine spindle in lieu of the usual wooden spools for this purpose. This is accomplished by inserting an instrument or spreader 20, such as a pencil or skewer, in the center corrugation and causing it to pass longitudinally through the corrugation so as to enlarge the center corrugation and cause the flat surfaces to be bowed as shown in Fig. 4. Because of the relationship of the winding extending over a large flat surface on either side of the spool, the sides can be readily bowed without interference by the .thread to the position shown in Fig. 4 and will maintain this relationship so as to receive the usual spindle of a sewing machine. If the base of the spindle is provided with the usual circular supporting member, the spool of the present invention will be supported thereby and operate smoothly during the operation of the machine. However, if such a circular base is not provided the usual metal shuttle bobbin may be first mounted on the spindle so as to provide the flat base for the spool and facilitate its unwinding.

Variations and modifications may be made within the scope of the claims and portions of the improvements may be used without others.
